if you have PRO CFW, then thats all you need...create a folder in PSP/GAME on your MS with the title of your game...place the EBOOT of your game inside that folder...now you should be able to play psx games on your psp...you must have a popsloader to play psx games without the need for an emulator...PRO Team coded it into their CFW, as is the case with pretty much any cfw above 6.20, eliminating the need for an external loader of any kind.
